HANGER FOR TROLLEY-WIRES.

SPECIFICATION forming part of Letters Patent No. 557,860, dated April'7, 1896.

Application filed June 24, 1895. Serial No. 553,871. (No model.)

To all whom it may concern.-

Be it known that LWILLIAM A. MQUALLUM, a citizen of the United States,and a resident of the village of Avondale, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inHangers for Trolley-Wires, of which the following is a specification.

The several features of my invention and the various advantagesresulting from their use conjointly or otherwise will be apparent fromthe following description and claims.

In the accompanying drawings, making part of this application, and inwhich similar letters of reference indicate corresponding parts, Figure1 represents a side elevation of a hanger embodying my invention. Fig. 2represents a vertical central section of the said hanger, taken in theplane of the dotted line 2 2 of Fig. 1. Fig. 3 represents a bottom viewof the said hanger with the lockingsleeve and insulator and suspensorybolt removed. Fig. 4 is a top View of the lockingsleeve. Fig. 5 is aside elevation of the same. Fig. 6 is a side elevation of the suspensorybolt and of its insulator. Fig. 7 represents a side elevation of myinvention, showing a different style of arms connected to the cap.

A indicates the cap orbell formed exteriorly to shed water. The cap isprovided with one or more arms A for supporting it. These arms may becurved, as shown in Fig. 1, or straight, as shown in Fig. 7. There maybe one or more of these arms in connection with the cap. For this reasonin Fig. 1 one of these arms is shown in solid lines, while the other armwhich may be added is shown in dotted lines. The interior of the cap isprovided with lugs, as B,alternated by recesses B The lock'sleeve C isprovided at its periphery with lugs C alternated by depressions O Thelugs C are so shaped and of such a size as respectively to easily passthrough the recess Each of the lugs O has an inclined bottom 0*, so thatwhen passed through the recesses O and the sleeve is rotated they shallelevate the sleeve and insulator and cause the upper end of the latterto come against the roof A of the cap, and thus hold the suspensory boltsteady. Within the sleeve is located the suspensory bolt D, upheld by aninsulator E. This insulator E surrounds and envclops the head D of thebolt and the upper portion of the shank D for a distance below thesleeve C.

The insulator E projects at its upper portion, the preferable shape ofsuch projection being a rim E, which latter rests upon the top of thesleeve, while the shank of the insulator extends down through and belowthe sleeve. The upper portion of the cap is turned out or recessed, sothat the head E of the insulator can closely enter and fit it, (the saidrecessed portion A.)

To the lower end of the bolt is connected the device Fviz., hook, ear,clip, and the like, as the case may bedirectly attached or connected tothe circuit or line wire. Such device is preferably screwed to the lowerend of the bolt D, the latter being in such event provided with ascrew-thread at D In the drawings Ihave shown an earscrewed to the boltD and upholding the line-wire G.

At one side the cap A is perforated at two points in line by openings,as A adapted to receive a pin B whose head 13 is shown in Fig. 1. Thispin is preferably a split one, that it may remain in place after beinginserted in position in the openings A The mode in which my inventionoperates is as follows: The cap A is secured in place by means of itsarm or arms A or equivalent means. The sleeve O is put in place on thesuspensory bolt. The suspensory bolt is con nected to the ears at thesame time as the latter is connected to the line-wire, or before orafter that event, according to the mode of attachment of the line-Wireto the ears. The sleeve O is now raised into the cap A and turned sothat the lugs O pass through the recesses B of the cap. The sleeve isnow rotated and its lugs 0 pass over onto the lugs B of the cap andraise the sleeve and bring the head D of the insulator against the roofA of the cap, thereby tightening the insulator and its bolt D in place.Those lugs G of the sleeve which are next to the openings will haveassumed the position shown in the dotted lines marked O of Fig. 3. Thesplit pin B is then passed into the openings A and against the adjacentsides of the lugs O 0 and prevents the sleeve C from turning in the capand thereby lockin g it into position. The operation is now completed.To remove the sleeve, insulator, and bolt 1) from the cap, theaforedescribed operation is reversed.

It will be observed that the cylindrical insulator allows the sleeve tobe rotated on it, and thus to be worked in introducing it, the sleeve,in place in the cap.

\Vhen desired, the projecting rim A of the cap maybe utilized as asurface against which the lugs C can impinge when introduced into thecap above the lugs B and rotated.

In order to obviate the necessity of grasping the sleeve 0 with thefingers when the latter operation becomes undesirable, I provide thesleeve with suitable detents for enabling a grappling iron or wrench toengage therewith. The preferred kind of detents are shown, and consistof the recesses C in the lower portion of the sleeve. Into theserecesses the teeth, hook, or projections of a suitable wrench areinserted and the sleeve rotated.

hat I claim as new and of my invention, and desire to secure by LettersPatent, is

1. In an electric-wire hanger, the combina tion of the bell-shaped bodyAhaving a roof in one piece therewith, and an insulated bolt, and asleeve-nut C, with projections, the bolt being supported by said nut,the body A being provided interiorly with projections for supporting theinsulator-bolt, when the nut O is rotated above and over saidprojections,substantially as and for the purposes specified.

2. In an electric-wire hanger, the combination of the cap A, havinginterior projections, and the sleeve carrying an insulatedsuspensorybolt,and having projections, for enabling the entering deviceswhen the sleeve is rotated to interlock with the cap, and thelocking-pin as B substantially as and for the purposes specified.

3. In aline-hanger, the combination of the cap having the interiorrecesses and projections, and the sleeve having corresponding exteriorprojections and recesses, and the sus pensory bolt, and surroundinginsulator, the projections having an inclined surface,whereby when thesleeve is interlocked, a portion of the entering device shall impingeagainst the cap and contribute to the steadiness wherewith the sleeveand what it carries are held in the cap, substantially as and for thepurposes specified.

4. In a line-hanger, the combination of the cap having the interiorrecesses and projections, and the sleeve having corresponding exteriorprojections and recesses, and the suspensory bolt, and surroundinginsulator, the projections having inclined surfaces, whereby when thesleeve is interlocked, a portion of the entering device shall impingeagainst the cap and contribute to the steadiness where with the sleeveand What it carries are held in the cap, and the pin as B impingingagainst the sleeve, substantially as and for the purposes specified.

5. An electric-line hanger, wherein is the combination of a cap having aseries of lugs B and alternate recesses B and a roof A and the sleeve 0having recesses C and lugs 0 having inclined faces 0 and the insulatorhaving head E supported by the sleeve, and a suspensory bolt envelopedby the insulator, the head E adapted to reach the roof when the sleeveis interlocked with the cap, substantially as and for the purposesspecified.

6. In an electric-line hanger, wherein is the combination of a caphaving a series of lugs 13 and alternate recesses 13*, and a roof A andthe sleeve 0 having recesses (J and lugs C having inclined faces C, andthe insulator having head E supported by the sleeve, and a suspensorybolt enveloped by the insulator, the head E adapted to reach the roofwhen the sleeve is interlocked with the cap, the cap having openings Aand the pin B received into said openings and bearing against the sidesof the adjacent lugs of the sleeve, substantially as and for thepurposes specified.

7.

8. An electric-line hanger, wherein is the combination of a cap having aseries of lugs B and alternate recesses B and a roof A and the sleeve 0having recesses (J and lugs 0 having inclined faces C and the insulatorhaving head E supported by the sleeve, and a suspensory bolt envelopedby the insulator, the head E adapted to reach the roof when the sleeveis interlocked with the cap, the cap having openings A and the pin 13*received into said openin and bearing again st the sides of the adjacentlugs of the sleeve, the sleeve being provided with the detents C,substantially as and for the purposes specified.
